The following will give you a list:

fileinput = open('tweets.txt', 'r')
lines = [line.lower() for line in fileinput]

If this is not what you're looking for, please clarify your requirements.

newLine = re.sub('[,]', '', lines) – Joe Kalvos Jan 04 '13 at 11:50
What are you expecting `re.sub()` to do here? It works on a string, and you're giving it a list. – NPE Jan 04 '13 at 11:50

The problem is that you are using the assignment operator =.

You need to change this to a += but you will lose the new line character \n.

I would suggest opening a list like this:

fileinput = open('tweets.txt', 'r')

lines = []

for line in fileinput:

   lines.append(line.lower())

Then you will have all lines in a list.

If you want to convert all the lines:

fileinput = open("tweets.txt", "r")
lowered = [l.lower() for l in fileinput]
